COMBINATION-TOOL.

Specification of Letters Patent.

Application filed Jjune 15, 1918. Serial No. 240,169.

To all whom it may concern:

Be it known that I, WILLIAM R. Jooss, a citizen of the United States, resldmg at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Combination- Tools, of which the following is a full, clear, and exact description.

This invention relates to a combination tool which is more particularly designed for the purpose of making measurements, and in certain respects is the equivalent of a tram mel, although it has other functions 1n addi- Fig. 3 is a bottom plan view; Fig. 4 is anelevation showing in more detail a portlon of the construction; Fig. 5 is a sectional elevation through a portion of the tool; Fig. 6 is a sectional elevation through another portion of the tool; Fig. 7 is a transverse section through aportion of the tool; Fig. 8 is an elevation more or less diagrammatic in character, showing certain of the implements forming a part of the tool; Fig. 9 is a side elevation of the construction shown in Fig. 8; Fig. 10 is a side elevation with portions in section of an implement for use in connection with the tool; Fig. 11 is an elevation of an implement used in connection with the tool; Fig. 12 is an elevation with portions in section of an implement adapted for use in connection with the tool; and Fig. 13 is an elevation of the implement shown in Fig. 12.

The device com rises a straight edge member which is in icated at 1. In order to adapt the tool for various, uses, this member 1 is provided with graduations in inches and fractions thereof, the fractions into which the inches are divided being varied so as to provide a plurality of scales measuring in eighths, sixteenths, thirty-seconds and sixtyfourths of an inch. Obviously the particular graduations mentioned are not in any sense limiting, as the scales having other degrees of graduation may be used with equal fashould be had to the accom-v cility. The straight edge 1, upon one side Patented Nov. 11, 1919.

thereof, is provided with-a groove 2, which extends longitudinally of the straight edge. This groove is preferably located at substan tially the center of the member 1.

Secured at one end of the straight edge is a fixture 3, this being immovable when once mounted uponthe straight edge, and is securedto the straight edge in a manner which will be subsequently described.

There is also a movable element or member 4 which has a part that engages with the groove 2 so that as the member 4 is moved along the member 1 it is guided by an edge of the member 1 and in part by the groove 2. The member 4 is provided with means by which when moved to any adjusted position upon the member 1 it may be clamped and held in its adjusted position.

The member 4 is provided with a part 5 which 'has a cylindrical opening therein in Y which is located a movable member 6. This member is notched out as indicated at 7 and has an extending part 8 upon which there is an inwardly extending foot 9. This foot is adapted to engage with the groove 2 of the straight edge 1, and an edge of the member 1 extends within the notched-out portion of the member 6.

The member 4 is slotted as indicated at 10 in Fig. 7, which slot receives the member 1.

' The member 6 at its upper end is provided with a screw-threaded shank 6, which in turn is engaged by a nut 11. This nut is hollowed out and within the hollowed-out portion is a spring 12 which bears against the top of the part 5. When the nut 11 is tightened it draws the member 6 upward and so holds the member 1 against theupper portion of the slot 10, thus preventing any sliding movement between the member 1 and the part 4.

The member 4 also has an extending part 13 which is provided with a cylindrical opening that receives a member 14. This member 14 at its outer end is provided with a threaded extension 14*, and upon the extension 14 is a nut 15, which bears upon the outer end of the part 13. The nut 15 is provided with a recess in which is seated a spring 16 that bears upon the outer end of the part 13.

The member 14 .is formed in the body thereof with a half-round groove 17 and this cooperates with a half-round groove 18 which is formed in the body of the part 4.

When the half-round groove 17 of the member 14 is in registry with the halt-round groove 18 it will be possible to pass through the registered grooves a shank 19, which shank may form a part of a suitable implement to be used in connection with the tool as will be subsequently described. When such a shank has been inserted, and the nut 15 tightened, it. draws the member 14 and so wedges the shank 19 to hold it in its adjusted position with respect to the member 4.

The member 4 has upon one face thereof a recessed portion, as indicated at 4 in Fig. 4. This recessed portion has an edge 4, which edge is in the same plane as the axis of the shank 19. The edge 4 is in contact with the straight edge 1 and may be moved in proximity to the scale graduations on the. straight edge 1, so that by reading the position of the edge 4 with respect to the scale on the member 1, it indicates the position of the axis of the shank 19 of an implement used inconnection with a tool.

The member 4 also has a part 13 through which there is formed a cylindrical opening which is adapted to receive the shank 19 of an implement as has before been indicated. Extending transversely with respect to the opening in the part 13 is the part 14.

At the lower end of the part 13 there is a notch as indicated at 21 which is adapted to receive a projection 25 which is formed of a part of the implement 26, the shank of which is indicated at 19. This projection and notch construction is for the purpose of definitely locating the implement with respect of the member 4 of the tool and prevent any rotation thereof.

It will be noted by referring to Fig. 7, that the member 14 in its normal position does not engage with the member 1 but stops short of such engagement so that the member 1 is permitted to move with respect to the member 4 and slide along the same.

The member 3 is in its general construction the same as member 4 with the exception that the member 24, which corresponds in function to the part 14 heretofore described, extends beyond the slot 25 in the member 3, which slot corresponds to the slot 10 of Fig. 7, and forms an abutment against which the end of the member 1 is adapted to engage and be positioned as indicated at 26 in Fig. 3. The end of the member 1 as it abuts against the part 24 of member 3 is in the same plane'as the axis in the shank 19 which is the shank of the implement cooperating with the member 3. This is indicated at 27 in Fig. 1. Therefore the center of the shank 19 is at zero or'the end of the scale of the member 1. It will thereforegbe clear that the distance measured on the sicale by the edge 4 as shown in Fig, 4 indiczit'cs the distance between the axes of the shanks 19 and 19 as shown in Fig. 1.

In connection with the shanks such as illustrated at 19 and 19*, various implements may be used. For instance, as shown in Fig. 11, the shank which is indicated at 19 may be provided with a pointed end as indicated at 28, in which event the tool may be utilized as a marking tool producingparallel lines, the distance between which can be definitely measured upon the scale of the member 1.

Or the implements used, may be such as indicated in Fig. 8, in which the shanks 19 are provided with head members 29 that have an edge 30, which edge is in line with the axis of the shank 19. These particular implements such as shown in Fig. 8, are convenient for measuring inside diameters, and the distance between the edges 30 as shown in Fig. 8 may be correctly read upon the scale of the member 1.

The particular arrangement of these implements as shown in Fig. 8 is intended for measuring interior diameters or interior distances, while with the arrangement of the same implements as shown in Fig. 1, in which the edges 30 are toward each other instead of away from each other, the tool may be used for measuring exterior diameter or distances.

As a modification of the particular implements shown in Fig. 8, there is shown in Fig. 10 a modified form in which the shank 19 is provided at the head portion with a roller 31, the surface of the roller being in line with the axis of the shank 19. The use of the implement shown in Fig. 10 is the same as the implement shown in Fig. 8, the difference being merely that the part which contacts with the object being measured provides a rolling contact instead of a nonrolling contact, the rolling contact being.

preferable particularly in measuring objects with a roughened surface.

In Figs. 12 and 13 there is shown what is known as a ball point. This implement is provided with a shank 19 which at its lower end is recessed, as indicated at 32, and the outer shell of the recess is slotted, as indicated at 33. The recess 32 is adapted to receive a pointed needle-like member 34. The outer surface of the split shell is tapered and receives a ball 35 which is provided with a tapered threaded opening. It will be I clear that when the ball 35 is turned upon the threads of the shell which holds the part 34, it will compress the same against the pin 34 and hold it in adjusted position.

The various implements which have been described, are all provided with shanks which make them suitable for use in connection with the parts 3 and 4 of the tool as shown in Fig. 1, and by the substitution of the various implements described, the tool may be employed for the various measuring purposes which have been indicated.
